Description
The Mishimoto Silicone Radiator Hose Kit (MMHOSE-WK2-12RD) replaces the factory rubber radiator hoses on the Jeep Grand Cherokee SRT and SRT8 with a 4-ply silicone upper and lower hose set built to handle more heat and pressure than stock rubber. Finished in red, this specific-fit kit is engineered around the coolant routing of the 6.4L V8-equipped Grand Cherokee and arrives with everything needed to complete the swap.
A cracked or leaking radiator hose can quickly turn into a serious cooling system failure and engine damage, which is why Mishimoto builds this cooling hose kit from high-grade silicone reinforced with four layers of heat-resistant embedded fibers. That construction gives the kit a maximum temperature rating of 330°F, and makes it just as suited to a stock daily driver as it is to a modified build. As a Performance-grade, specific-fit cooling component, it’s a straightforward way to add durability and peace of mind to your Grand Cherokee’s cooling system.
